SNAP GAUG E Filed June 4, 1929 @M1115 @myZ/n avmgow Patented Oct. 18, 1932 UNrrElo STATES PATENT Y OFFICE- ERIK H. ALDER-BOR-GrH,` OLE IOGHKEEPSIE, NEW YORK, ASSIGNOR T STANDARD GAGE COMPANY, INC., OF POUGHKEEPSIE, NEWfYORK, A CORPORATION OIE N EW YORK `SNAP GAUGE Application filed June 4, 1929. Serial No. 368,291.

This invention relates to a snap gauge and more particularly to a novel construction of the gauge frame, whereby a finger grip is provided without adding either weight to the gauge or weakening the frame by removing metal therefrom to form the finger holds.

To facilitate proper use and ease of operation of a snap gauge of the C-type,a means for holding the same must be provided and this lo has heretofore been done either by forming a boss on either or both sides of the frame, in which case additional `weight is added, 'or by milling or cutting a slot on both sides, of the frame to provide a finger hold, and in this f case metal is removed which not only tends to weaken the frame but permits changes to take place due to strains in the metal caused by eX- pansion and contraction during use which will cause the gauge to become inaccurate.

The object of the present invention is to provide a snap gauge so constructed that an ideal nger grip is provided without either adding or subtracting any metal to the frame.

Another object being that by this construction the frame is made more rigid as the cross section is of suoli a form as to add strength without weight.

With these and other objects in view, my invention consists in certain construction and combination of parts asvvill hereinafter be fully described and claimed, and fully illustrated in the accompanying drawing which forms a part of this disclosure and in which like figures of reference refer to corresponding parts in all of the views, but it is understood that slight changes may be made without departing from the spirit of the invention.

In the drawing Figure 1 shows the usual form lof snapv gauge, but including my construction.

Figure 2 is an edge view of the same. Figure 3 is a cross sectional view on the line A-B of Figure 1. Referring tov the drawing f5 i The frame 10 is formed with a body or web 10 provided with the ends 11 in which` are mounted the usual gauge pins; the web 10 being formed with the lower beading-12 land the upper beading 13, which makes a finished 0 edge and adds strength to the frame. There is also provided the pad 14 and name plate l5.

At a point near the top of the frame 10 is formed a beading 16 which together with the beading 13 forms a finger hold or grip 17, the sides sloping inward as shown in Figure 3, and in cross section the bottom thickness being equal to that of the web l0, and by this construction an ideal finger grip, is provided without adding metal or removing metal from the frame, and by the use of the beading 16 a frame is provided which is very strong in cross sect-ion.

W'hile the finger grip shown is of oval shape, it is to be understood that it may be of any suitable shape and size, and also that the location may be changed should it be desired to place the same nearer one end.

Also be it understood that several of these nger grips may be employed if desired should the gauge be large and heavy.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

A snap gauge comprising a C-shaped type frame having a marginal beading and formed with an eliptical shaped depression on each side thereof and in registry with each other, a raised edge `surrounding said depression and forming a part of the beading of said frame.

In testimony whereof I affix my signature.
